Ok, so I've searched the forums and have come really really close, but just need a bit of help tweeking here ...I would like to change the bookmarks in Acobat PDF to Sentence case.eg: tommy went to the well > Tommy went to the well

That worked great - but to go through all the bookmarks to change the first letter is proving to be a bigger mission then I anticipated. Can anyone assist in tweaking the above coding so that it converts to Sentence case, or perhaps provide another solution?
